Abstract

In this contribution the existing RPAT concept
for simultaneous approaches to closely spaced
parallel runways is further elaborated to be
implemented in low visibility. Besides RNP
capabilities this concept uses as well airborne interval
management capabilities. The basic procedure design
aspects and the required airborne functions are
described. The airborne spacing will first be initiated
by a 4D approach in which the trajectory of the target
aircraft is being predicted based on position
information provided by ADS-B or TIS-B. The
interval management function itself is then used to
adjust the spacing such that after the S-curve the
RPAT aircraft is parallel or slightly behind the target
aircraft. Besides the basic concept and the
technologies used, results from flight trials will be
reported.
